I am very new to Klipper and really want to give it a try. I just finished building a Cartesian style printer with an Octopus Pro board and want to run the Klipper firmware on it. I have always been hardcore Marlin when it comes to firmware but only because I understand it well. I have been able to flash the Octopus Pro with the Klipper firmware without issue. I am using Mainsail with Klipper and have everything installed onto my Pi. I can access the Pi through SSH and Mainsail is working fine.  
My problem is the lack of confidence in my own work. I’d love for someone to help me Sanity check my printer.cfg file. I used the example configuration from Klipper but I have a lot of extras I need help with.

I have an MKS PWC power module connected to the Octopus Pro in the power detect connector. I also have a BigTreeTech 24 volt UPS module. Would I need to define the pins for these two?  
I am also having trouble with setting up the Z tilt. I have been over the Klipper information 20 times and still don’t get it. Do I need to define the voltage in Klipper?  
I will include my printer.cfg info below if anyone here can take a look and see if they spot anything I may have missed or got wrong.

My setup:  
Cartesian style printer  
Octopus Pro main board  
24 volt power supply  
Nema 17 motors  
TMC2209 (BTT) drivers in UART mode  
Dual Z drivers  
300 by 300 mm heated bed  
MKS PWC power module  
24 volt UPS (BTT)  
TFT35 v3.0 (BTT)  
Dragon hot end  
dual part cooling fans  
separate cooling fan on the TMC drivers

Hello @cabinfourus !

Can you please put your file inside the code markers you find in the editor tool bar. So it’s more easy to read and characters don’t get lost.

Sorry, I am not sure how. I will see if I can figure it out though.
